Title Body

I am trying to make an app that records a video using the camera app, and then saves that video on SD card so I can play it. I have some code but I'm lost on how to continue as I'm a beginner in Android. My Activity: public class Camcorder extends Activity { private CamcorderView camcorderView; private boolean recording = false; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //irrelevant code camcorderView = (CamcorderView) findViewById(R.id.camcorder_preview); } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { if (keyCode == KeyEvent.KEYCODE_DPAD_CENTER) { if (recording) { camcorderView.stopRecording(); finish(); } else { recording = true; camcorderView.startRecording(); } return true; } return super.onKeyDown(keyCode, event); } } CamcorderView class: public class CamcorderView extends SurfaceView implements SurfaceHolder.Callback { MediaRecorder recorder; SurfaceHolder holder; String outputFile = "/sdcard/default.mp4"; public CamcorderView(Context context, AttributeSet attrs) { super(context, attrs); holder = getHolder(); holder.addCallback(this); holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); recorder = new MediaRecorder(); recorder.setAudioSource(MediaRecorder.AudioSource.MIC); recorder.setVideoSource(MediaRecorder.VideoSource.DEFAULT); recorder.setOutputFormat(MediaRecorder.OutputFormat.MPEG_4); recorder.setAudioEncoder(MediaRecorder.AudioEncoder.AMR_NB); recorder.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP); // recorder.setVideoSize(480, 320); // recorder.se
